WINDOW SCREEN.

Application filed September 5, 1922. Serial No. 586,297. i

1 0 all whom it may concern:

Be it known that I, MARGARET SMITH, a citizen of the Dominion of Canada, and resident of Owen Sound, in the county of (ire and Province of Ontario, Dominion of anada, hav invented certain new and useful Improvements in /Vindow Screens, of which the following is a specification.

This invention has relation to certain new and useful improvements in window screens and has for its primary object the provision of sectional adjustable window screens which may be readily app-lied and left in the window frame without interference with operation of the inner or lower 1 sash.

; tion of the screen section so as to permit 7 flies and the like to pass through the window.

Another object of the invention resides in the provision of adjustable window screens of the character stated which will be composed of the minimum number of parts of simple construction and arrangement and which may be readily adjusted, as desired.

A still further object of the invention resides in the provision of adjustable and sectional window screens of the character stated which may be readily adjusted in the supporting members provided for mounting the screens in the window frames opposite one of the adjustable window sashes.

Still another objectof the invention resides in the provision of sectional adjustable window screens of the character stated in which the sections will be of special con struction so as to securely retain th edges of the wire mesh members in the retaining edge members of the sections and these various sections held by the supporting members in close overlapping relation so as to prevent flies and the like from passing in or out of the window between the screen sections.

With the foregoing and other objects in view as will appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of co -operating elements as hereinafter more specifically set forth, claimed and shown in the accompanying drawings forming a part of the present application in which Fig.1 isan elevation of the lower portion of a window with the improved window screen in use and, showing the sections in their extended positions. I

Fig. 2 is an enlarged detail fragmentary perspective view of the screen, showing the manner of overlapping the sections thereof.

Fig. 3 is an enlarged fragmentary horizontal section substantially on the plane of line 3-3 of Fig. 1', looking in the direction indicated by the arrows.

Fig. 4 is an enlarged fragmentary detail perspective view of a corner of one of the sections to disclose the construction thereof.

Fig. 5 is an enlarged fragmentary elevation of one of the supporting and guiding members, showing the manner of mounting the same. e I i Fig. 6 is a fragmentary vertical section substantially on the plane of line'66 of Fig. 5, looking in the direction indicated by the arrows.

Referring more in detail to the. drawings in which similar reference characters designate corresponding parts throughout the several views, 10 designates the window sill, 11 a sliding window sash and 12 the side frame members of a window to which the improved window screen is adapted.

In constructing the window screen the supporting and guiding members 13 are employed and mounted vertically in the side frame members 12 between the beads or guide strips 14: for the sliding window sash 11. When the screen is mounted as shown in the drawings, the supporting and guiding members 13 are positioned beneath the upper or outer sliding window sash 11. Each supporting and guiding member 13 is composed of'a metallic plate bent to form an outwardly directed central rib 15, after which the sides of the plate are bent outwardly andthen toward one. another to cooperate withthe outwardly directed central rib 15 in forming parallel'guide pockets 16 of rectangular form inend elevation and extending practically the entire length of the supporting and guiding member 13.

The parallel guide pockets 16 are both open ill) ill

ing and guiding members 13 the ends of the plates from which the supporting and guiding members 13 are formed are left fiat and extended a short distance to either side to form the ears 17 having elongated slots 18 provided therein and through which thesecuring screws 19 are extended, these securing screws 19 having heads 20 which are turned across the elongated slots 18 to retain the supporting and guiding members 3 in position. Vi hen it is desired to remove the supporting and guiding members 13, it .is simply necessary to give the securing screws 19 a quarter turn to bring the heads 20 thereof into registration with the elongated slots 18 and then lift off the supporting and guiding members 18. These supporting and guiding members 13 may be just as readily mounted on the securing screws 19 and the securing screws 19 then turned to bring the heads 20 thereof across the elongated slots s.

Each screen section comprises a rectangular body 21 of line wire mesh or other suitable material. The upper and lower edges of the rectangular body 21 are secured in the upper and lower frame members 22 which are formed of narrow metallic strips bent upon themselves longitudinally and centrally and clamping on opposite sides of the upper and lower edges of the wire mesh composing the rectangular body 21. This may be readily understood by referring to Figs. 2 and 4:. The inner vertical edge of each screen section is also formed of a frame member 23 corresponding to the upper and lower frame members 22, with the exception that the ends of the frame members 23 are extended and bent upon themselves in rectangular form to produce the rectangular guides 24 for the upper and lower frame members 22. It is to be understood that the upper and lower frame members of each screen section slide through the rectangular guides 24 of the overlapping screen section with which the first mentioned screen section is adjustable transversely of the window. This should be apparent by reference to Fig. 2 as well as Fig. 1.

In order that the overlapping screen sections may be adjustable vertically of the window, each screen section has an outer end frame member 25 within which the outer vertical edge of the rectangular body 21 of the screen section is secured. The outer end frame member 25 is composed of a pair of solid members of triangular form in end elevation .and placed with their wide flat faces opposite to one another and on opposite sides of the rectangular body 21, after which the securing members 26 are passed through the triangular members and through the rectangular body 21 from the opposite edges of said members, as shown in Fig. 4. It will therefore be seen that the complete outer end frame member for each screen section is of rectangular form in end elevation and by reference to Fig, 3 it will be seen that each outer end frame member 25 is arranged for adjustment in one of the parallel guide pockets 16 of the supporting and guiding members 13. In order to retain the screen sections in their adjusted positions vertically of the window, set screws 27 are threaded in the walls of the parallel guide pockets 16, near the open longitudinal inner corners 16 thereof. it is evident that these set screws 2? may be tightened to press apart the outer end frame members 25 within the parallel guide pockets 16 and thereby prevent sliding movement of the outer end frame members 25 in the parallel guide pockets 16. For the purpose of raising and lowering the screen sections when the screws 27 are loosened, each screen section is provided with a lifting hook 28 either above or below the supporting and guiding menrbers 13, according to the position of the screen section and the guide pockets 16 witlr in which the screen section slides.

it believed the complete construction and operation of the screen may now be clearly understood from the foregoing paragraphs taken in connection with the accompanying drawings without further detail description. It may be briefly stated, however, that the supporting and guiding memhere 18 may be readily positioned on the side frame members 12 of the window to which the screen is to be applied and the screen sections connected in pairs, as shown in 1 and 2 for adjustment transversely of the window and then the pairs of screen sections mounted in the support ing and guiding members 18 for adjustment vertically of the window, as previously described and as clearly shown in Fig l. The screen, when properly adjusted, will extend downwardly to the window sill l0 and upwardly to the sliding window sash 11 beneath which the screen is positioned as well as projecting to either side of the window frame. The close engagement of the overlapped edges of the screen sections will prevent flies or the like from passing through the window between the screen sections. It is therefore evident that a simple and inexpensive form of sectional adjustable screen is provided which may not only be readily mounted in the window frame and removed but will also be highly efficient in use. When not required for use, the screen may be stored away in compact form with the screen sections practically parallel to one another or disconnected and removed from the supporting and guiding members 13.

While the preferred embodiment of the invention has been disclosed, it is to be understood that minor changes in the de tails of construction, combination and arrangement of co-operating elements may be resorted to within the scope of what ,is claimed without departing from the spirit of the invention.

What I claim as new is:

1. An adjustable sectional screen com-' prising supporting and guiding members formed with parallel pockets extending lon gitudinally thereof; said supporting and guiding members being adapted for detachable mounting on a window casing; screen sections arranged in transversely adjustable pairs; said pairs of screen sections being adjustable in said supporting and guiding members, whereby the screen may be adjusted vertically of the window; and means for securing said screen sections in their vertical adjusted positions within said supporting and guiding members.

2. An adjustable sectional screen comprising supporting and guiding members adapted for detachable mounting on a window casing; said supporting and guiding members being formed with parallel pockets of rectangular form in end elevation and having a common opening at their inner connecting corners; screen sections ar-' ranged in upper and lower pairs having their meeting vertical edges overlapped whereby said sections may slide upon one another; said sections having outer vertical frame members arranged for sliding engagement in said pockets of the supporting and guiding members; said upper and lower pairs of screen sections being adjustable vertically of the window and independently of one another; and means for securing said pairs of screen sections in adjusted position within said supporting and guiding members.

3. An adjustable sectional screen comprising screen sectionsof rectangular form; the lower portion of said screen sections carrying guide members at their upper edges, whereby said sections may slide transversely of one another for adjustment across a window; supporting and guiding members adapted for detachable mounting in a window frame to support the screen sections in alignment with one of the Window sashes;said supporting and guiding members having a central rib with pockets on opposite sides thereof; said screen sections being mounted in pairs in said pockets and adapted for adjustment Vertically of the window to bring the upper and lower pairs of screen sections into engagement with the window sill andthe window sash; lifting hooks carried by' said screen sections; and means carried by said supporting and guiding members for retaining the pairs of screen sections in their vertically adjusted positions.

4. In an adjustable sectional screen, a supporting and guiding member embodying a plate bent to form a central rib and then outwardly and then'at angles to form parallel guide pockets upon opposite sides of said rib with their adjacent edges spaced opposite said rib.

5. In an adjustable sectional screen, a

supporting and guiding member embodying a plate bent to form a central rib and then outwardly and then at angles to form parallel guide pockets upon opposite sides of said rib with their adjacent edges spaced opposite said rib, and outer frame members each composed of a pair of members of triangular form engaged in said guide pockets.

In testimony whereof, I aflix my signature.

MARGARET SMITH.
